AI-summarised brief · reviewed before publication
Apple has rolled out the second round of beta builds for its current-generation operating systems, including iOS 18.6, iPadOS 18.6, macOS 15.6, watchOS 11.6, tvOS 18.6, and visionOS 2.6. These new builds are now available for testing by developers. The second iOS 18.6 and iPadOS 18.6 developer betas have a build number of 22G5064d, replacing the initial 22G5054d build. Similarly, the second macOS Sequoia 15.6 build has a build number of 24G5065c, up from 24G5054d. The second tvOS 18.6 build has a build number of 22M5065b, replacing 22M5054b, while the second watchOS 11.6 build has a build number of 22U5065c, taking over from 22U5054b. Lastly, the second visionOS 2.6 build has a build number of 22O5764b, up from 22O5754c. It is worth noting that these beta builds are running alongside a separate milestone update version, which is currently testing iOS 26, iPadOS 26, macOS 26, watchOS 26, tvOS 26, and visionOS 26. As expected, the content of these developer betas is minimal, with a focus on new features in the fall software releases. However, they are likely to include performance and security updates as well. AppleInsider and Apple itself strongly advise against installing beta operating systems or other software being tested on "mission-critical" or primary hardware, due to the potential risk of bugs and issues that could result in data loss. Instead, testers are recommended to use secondary or non-essential devices and ensure they have sufficient backups of their data.
